This invention relates to improvements in control devices, for supplying gas and other combustible fuel thru a carburetter or other mechanical valve, to the engines of automobiles and other motor driven vehicles.

An object of this invention is to provide an automatic controlled device, to regulate a steady flow of fuel to the engines of motor driven vehicles, without the use of hand operated controls. A further object of this invention is to provide an automatic device, that will hold the fuel feeding apparatus at any open position, to attain any travelling rate of speed desired, injecting a steady even flow of fuel to the motor of a vehicle, eliminating an uneven supply of fuel causing a jerky ride. I

Another object of this invention, is to provide an automatic control device, that after the desired speed of the motor vehicleis attained, the

operator can maintain that speed without con hold the fuel feeding apparatus operated with the foot, open at any depressed position, eliminating foot and leg' ache, thru the necessity of constant pressure as is customary with devices now used.

an automatic control device, that canbe made operative with a slight touch of the operator's: foot, to hold the throttle pedal depressed, :or the: fuel feeding apparatus open andonethat can instantly be made inoperative, by quickly depressing the throttle pedal to the floor, or fully depressing the clutch pedal. v

Still a further object of this invention, is to provide a device, that will automatically idle the speed of the motor the same as removing pressure by the foot upon the throttle pedal used in automobiles, trucks and other vehicles operated on the same principle, by slightly depressing the clutch or brake pedal.

A iurther object, is to provide an automatic throttle control device, that can be installed with equipment now in use on all motor driven vehicles, one that can. be installed in the manufacture and a device that, will operate reasonably ent day motor driven vehicles and one that can be manufactured at a very nominal cost.

Other advantages will appear in the following specification and all novel features will be pointed out in the appending claims.

An embodiment of this invention, is shown in the drawings herewith, which'form a part of this application in which Figure 1 is a top view of the cup shaped case.

board assembly'of the automatic throttle control device' and the combination with the throttle, ,clutcl'ilandbrake pedals.

Referring to the drawings, it will be seen this automatic throttle control device consists of a cup shaped metal body III, with a flanged top I l, aperture guides 13 and M in the base of the cup and a bar or means l5 oiiset from the center, fixedly fastened between the top and base, to the wall inside the said cup, shown in Figure l. Apertures I: in the flange are for assembly.

In Figure 2 I have shown the throttle pedal control rod [6, the upper end of which is bossed, is inserted thru aperture guide l4 in the base of the cupped case !0. Figure 3, a loosely coiled spring I1, is placed over the bossed end of the throttle pedal control rod l6 resting in the base of the cupped case l0. Figure 4-shows a disc or holding means l8 with a U slot IS on the edge, a tail section 20 remote from said U slot, with an oval aperture 2| in the center, the said disc is inserted into the cup shaped case III, with the tail section 20 under the bar or means is, over the spring I1 and the throttle pedal control rod I8, continues thru the oval aperture 2| in the disc or holding means I8. The control release lock shaft 22, shown in Figure 5, is inserted thru the U slot I9, in the disc or holding means l8 and thru the aperture guide I3 in the base of the cupped body I8, with the pin 23 horizontally thru the center, resting on the upper side of the disc I8, shown in Figure 10, an enlarged sectional elevation of Figure 7 on a'plane of the line I8--I8 of Figure 7.

Figure 6 depicts a cover plate 26, with an oval aperture 21 in the center, thru which is projected the bossed end of the throttle pedal control rod I6 and aperture seat 28, thru which projects the upper end of the control release lock shaft 22, a threaded adjustment cap 25 is assembled to the upper end of the said control release lock shaft and a miniature coil spring 29 is inserted in aperture 28 of the cover plate 26 behind the control release lock shaft 22, shown in Figure 8, the said cover plate 26 is assembled to the flanged top I I, of the cupped case I8 with threaded studs inserted thru apertures I2 in the flanged top and I2A in the cover plate shown in Figure 7.

In Figure 10 I have shown an enlarged sectional elevation of Figure 7, on a plane of the line I8-I8 of Figure '7, to clarify the assembly and simplify the understanding and cooperation of the units comprising the device. Reference to Figure 8, the notch 24 in the control release lock shaft 22 is dislodged from aperture seat 28 in the cover plate 26, causing the upward movement of the disc or holding means I8 thru pressure of the coil spring I'I, shown in Figure 9, said disc being anchored under the bar or means I in the cupped body I8. The upward movement of the disc or holding means I8, grips the throttle pedal control rod I6 at the oval aperture 2| in said disc or holding means thru which said rod projects and so long as the disc or holding means I8 is free from pressure of the pin 23 in the control release lock shaft 22, the said disc or holding. means I8 can move up and down as if hinged, allowing the throttle pedal control rod I6 to move downward,

the disc or holding means I8 gripping it on;,the

upward movement at aperture 2| of the-said disc or holding means, thru pressure of the coil spring around the throttle pedal control rod I3 and under the disc or holding means I8. Depressing the control release lock shaft 22, forces the disc or holding means I8 down by the pin 23 therethru, releasing the grip of the oval aperture 2| in the disc or holding means I8 on the throttle pedal control rod I6, allowing the upward movement of said rod.

Referring to Figure 10, the control release look I shaft is shown with the notch 24 therein seated in aperture seat 28 of the cover plate 26, holding the disc or gripping means I8 horizontal with the base of the cupped case I8, releasing all pressure upon the throttle pedal control ,rod I6; allowing said rod to move up and down freely thru aperture I4 in the cupped case I8, oval aperture 2| in the disc or gripping means I8 and oval aperture 21 in the cover plate 26.

In Figure 11, I have shown the mechanism on the under side of the floor-board 3| of a motor vehicle to operate the control release lock shaft 22 with the clutch and brake pedals 44 and 45, consisting of a formed rod 32 with an eye 33 at one end loosely fitted to the lower end of the control release lock shaft 22 extending thru the base of the cupped body I8, with a pin 34 inserted thru the end of said shaft, the remoteend of rod 32 having an eye 35 extending downward from the floor-board 3|, said rod is fastened into position with loosely fitted bearing cleats 36 attached to the floor-board 3| allowing free manipulation of said rod. A formed rod 31 threaded at one end is inserted into eye 35 of rod 32 with a nut 38 for adjustment, the remote end of rod 31 being assembled thru a cylindrical cam coupling 39, fixedly fastened to the floor-board with a cleat 48. A rod 4I fixedly fastened to the cylindrical wall of the said coupling with an eye 42 at the remote end thereof, to which is assembled a bar 43 extending across the under side of the clutch and brake extension arms 44 and 45, said bar is affixed in place with a threaded stud 46. Depressing either the clutch pedal 44 or the brake pedal 45 forces the bar 43 down, opening the seat 4'! in the cam coupling 39 (shown in Figure 12) thereby manipulating rod 32 drawing down the control release lock shaft 22, the same as depressing it from the top, a coil spring 48 around the movable end of the cam coupling 39, returns bar 43 toits original position and a coil spring 49 threaded upon rod 31', draws the said cam coupling into its seat 41 when tension is removed from the clutch and brake pedals 44 and 45.

In Figure 13 I have shown the floor-board 3|, a throttle pedal 58 to which is attached a control rod 5|, used to operate the fuel supply of modern motor driven vehicles, the cup shaped body I8, into which is assembled the units shown in Figures 2 to 5 consisting of a throttle pedal control rod I6, a coil spring II, a disc or gripping means I8 and a control release lock shaft 22 with a cover plate 26 comprising this automatic throttle control device is inserted thru or attached to the under side of the floor-board 3| beneath the throttle pedal 58 and fixedly fastened with studs 38, thebossed end of the throttle pedal control rod I6 is assembled to the under side of the throttle pedal 58 with a coupling means 52. Referring to Figure 10, the notch 24 in the control release I lock shaft 22 is shown seated into aperture seat 28 in the cover plate 26. Dislodging notch 24 from the said seat 28 causes the said disc or gripping means I8 to raise thru pressure of the coil spring II, said disc or gripping means on the upward movement, grips by friction the throttle pedal control rod I6 as formerly stated. The throttle pedal control rod I6 attached to the throttle pedal 58, is forced downward with the said pedal, as shown by the broken lines of the pedal, increasing the fuel supply to the motor regulating the speed of travel and the operators foot can be removed from the said'pedal when th desired speed is attained and an even flow of fuel is continued until the throttle pedal control rod I9 is released by slightly depressing the clutch or brake pedals 44 and 45 as shown by the broken lines of'extension arm 44 depressed. This action of the pedals forces down rod 4| attached to the wall of the cylindrical cam coupling 39 opening the seat 41 in the said coupling, (shown in Figure 12) the formed rod 31, loosely fitted thru the cam coupling 39 and assembled thru eye 35 extending downward from the floor-board 3|, manipulates formed rod 32 when the said cam coupling is forced open and eye 33 assembled to the lower end of the control release lock shaft 22 draws the said shaft down as stated before,,forcing the disc or holding means I8 down also, releasing the grip of oval aperture 2| in the said disc or holding means on the throttle pedal control rod I6, allowing the throttle pedal 58 to return to its original position as before depressing, lessening the fuel supply to the motor.

ll, forces the control release lock shaft 22 down and notch 24 therein seats into aperture seat 28 of the cover plate 26 by the pressure of the miniature spring 29, shown in Figure 8. The same result can be obtained by depressing the clutch pedal 44 to the floor as when shifting gears. When notch 24 in the control release lock shaft 22 is seated as shown in Figure 10, it brings in line guiding aperture H in the base of the cup body It, oval aperture in the disc or holding means I8 and oval aperture 21 in the cover'plate 2i, freeing the throttle pedal control rod It to allow it to move up and down freely as before installation of my device.
